AMPHIBIANSAmphibians are cold blooded, breathe air through
their skin and do not have hair or scales. Amphibians go through a
metamorphosis; starting from an egg, morphing into larvae that is
typically aquatic, breathing by gills, and growing into semi-terrestrial
adults that breathe by lungs and through moist skin.
REPTILE OR AMPHIBIAN?Amphibious
means ‘belonging to both land and water’ - but not all amphibious
creatures are amphibians. Marine iguanas, sea snakes, crocodiles and
pond turtles are all amphibious but they are considered reptiles because
they do not go through a metamorphosis. They also have scales;
amphibians have no scales. While both amphibians and reptiles come from
eggs, amphibian eggs need to stay moist or wet as they develop and are
usually laid in water.
